Atomos ATOMSUMSE1 Sumo 19SE – 19" HDR Monitor-Recorder-Switcher

Product Overview

The Atomos Sumo 19SE is a 19-inch 1200-nit HDR touchscreen monitor-recorder-switcher designed for multi-camera production, live event coverage, and on-set monitoring workflows that require a single unit to handle monitoring, recording, and live switching. Built around a DCI-P3 SuperAtom IPS panel with a Full HD display, the Sumo 19SE records up to 4K RAW and 4Kp60 via SDI and HDMI inputs, switches up to four 1080p60 ISO feeds simultaneously, and outputs a switched program channel for downstream broadcast or streaming. At $1,995 MSRP, it is the professional standard for productions that need a large-format central control hub without the cost of separate monitoring, recording, and switching hardware.

Product Description

The Atomos Sumo 19SE consolidates three production tools—monitor, recorder, and switcher—into a single 19-inch touchscreen unit suited for video village setups, corporate AV production, house of worship broadcasts, and live event multi-camera workflows. The 1200-nit DCI-P3 display renders HDR footage accurately in both indoor and outdoor lighting conditions, while the comprehensive monitoring toolset keeps focus, exposure, and composition tools accessible without interrupting the live feed.

Recording captures Apple ProRes RAW up to 6Kp30 and 4Kp60 directly from 12G-SDI sources, along with ProRes HQ/422/LT and Avid DNxHD/DNxHR to removable SSD. In multi-camera setups, the Sumo 19SE records up to four simultaneous 1080p60 ISO streams via 3G-SDI Level A inputs, plus a fifth switched program channel—giving editors individual camera feeds and the live-switched cut in a single recording session. Switching between ISO feeds is handled from the touchscreen in real time with asynchronous source support, so cameras do not need to be genlocked to one another.

For signal conversion and routing, the Sumo 19SE cross-converts between HDMI and SDI. LTC timecode input via BNC supports multi-camera synchronization. Genlock accepts an external reference signal for playback-mode locking. Audio handling includes dual 3-pin XLR balanced inputs and outputs at 24-bit/48 kHz, plus built-in 5W speakers and a headphone output. Power draws from dual 4-pin XLR inputs for continuous battery-switched field operation, compatible with V-Lock and Anton Bauer batteries via optional mounting plates. Teams looking for a companion on-camera recorder to complement the Sumo 19SE can browse compatible Atomos Ninja and Shogun monitors at Creation Networks.

Frequently Asked Questions

How many cameras can the Sumo 19SE switch between simultaneously?
The Sumo 19SE switches between up to four 3G-SDI Level A camera inputs in real time from the touchscreen, without requiring genlocked sources. It simultaneously records each feed as an individual ISO plus a fifth switched program channel.

What recording formats does the Sumo 19SE support?
Apple ProRes RAW (up to 6Kp30 from 12G-SDI), Apple ProRes HQ/422/LT, Avid DNxHD, and Avid DNxHR. All record to SATA SSD via the Master Caddy system.

Does the Sumo 19SE have audio inputs?
Yes. It includes two balanced 3-pin XLR inputs with 48V phantom power, two balanced XLR outputs, built-in 5W speakers, and a 3.5mm headphone output. Audio is recorded at 24-bit/48 kHz PCM.

Can the Sumo 19SE be used with non-genlocked cameras?
Yes. Asynchronous switching removes the need for genlocked sources, making it possible to mix camera brands and models without additional sync equipment.

Does it support timecode synchronization?
Yes. The Sumo 19SE accepts LTC timecode via BNC input in record mode and supports HDMI/SDI embedded timecode. Genlock is supported in playback mode.

What power does the Sumo 19SE require?
DC 12V–16.8V at 75W. Continuous dual battery operation via two 4-pin XLR inputs; V-Lock and Anton Bauer gold-mount batteries are supported via optional mounting plates.

Is the Sumo 19SE calibration-ready?
Yes. It is compatible with the Atomos Calibrator app and Calibrite ColorChecker Display Pro or Display Plus probes for verified HDR and Rec.709 accuracy.
